STOP FOR TALKING-MACHINES.

Specification of Letters Patent.

Patented Mar. 12, 1918.

Application filed June 22, 1917. Serial No. 176,370.

To all whom it may concern:

Be it known that I, J AMES S. LANE, a citizen of the United States,residing at Snohomish, in the county of Snohomish, State of iVashington,have invented a new and useful Stop for Talking-Machines; and I doherethe tone or sound arm for stopping the turn table that supports therecord.

A further object of the invention is the provision of a device of thiskind having an oscillatory spring tension frame or bracket mounted upona plate and provided with a screw to be adjusted according tograduations upon a dial, whereby, as the stylus or needle reaches theend of the sound groove of the record, the tone or sound arm will engagethe end of the abutment screw and cause the frame or bracket tooscillate incident to the tension of its spring, thereby applying abuffer to the turn table for stopping the same.

A further object of the invention is the provision of a dial and anabutment screw threaded through itscenter, and having an arm to overlieand register with any one of the graduations of the dial in accordancewith the ending of the sound groove of the record, whereby thetone armmay contact with said screw tooscillate said frame or bracket. Thisabutment screw may be provided with any number of threads, each of anysuitable pitch in accordance with the graduations of the-dial and viceversa. In other words, the graduations of the dial may be variedaccording to the pitch and the number of threads.

In practical fields, the details of construc tion may necessitatealterations falling within the scope of what is claimed.

The invention comprises further features and combination of parts, ashereinafter set forth, shown inthe drawings and claimed.

In the drawings Figure 1 is a plan view of a portion of a talkingmachine, showing the improved stopping device applied, whereby thetoneor sound arm may automatically actuate the stopping device.

Fig. 2 is a plan view showing the stopping device as having beenactuated.

Fig. 8 is a view in side elevation of the stopping device, showing thesame on an enlarged scale.

' Fig. 4 is a view in elevation at right angles to that illustrated inFig. 3.

Referring more especially to the drawmgs, 1 designates a portion of thecasing of a talking machine, and in which casing the motor, not shown,for driving the record supporting turn table 2 is designed to bearranged. Swiveled in a conventional man nor on the casing 1, whereby itmay oscillate across the record is a conventional form of tone or soundarm 3, which is provided with the usual coupled vertically oscillatorysection 4 which is supplied with the sound box 5 having the stylus orneedle 6. A partial circular supporting plate 7 is provided, the samehaving laterally extending perforated ears 8. Said ears are bentdownwardly so as to hold said plate spaced at an interval above thecasing 1, there being suitable screws 9 passing through .theperforations of the ears, to fasten the plate firmly to the casing. Thecenter of the plate 7 has a perforation or aperture 10, for thereception of a pivot bolt 11, the head of which is arranged between theplate 7 and the upper face of the casing. This bolt 11 passes centrallythrough the circular base 12 of the oscillatory bracket 13, there beinga suitable washer or circular plate 14 interposed between the base 12and the plate 7, thereby holding the base of the bracket spaced fromtheplate 7. These interengaging parts may be well lubricated, so that thebracket will easily and freely oscillate a limited distance. Projectingfrom the marginal edge of the circular base of the bracket is aprojection 15, the end of which is provided with oppositely disposedupwardly extending long and short arms 16 and 17. The long arm 16 has atits upper end an overhanging curved hook is, to be engaged by anoperators finger for resetting the oscillatory frame or bracket. Theshort arm 16 is provi'dedwith a substantially key-hole shaped slot- '19,in the larger end of which a suit- V able buffer 20, constructed of anysuitable fiber, either leather or rubber, adapted to engage the marginaledge of the turn table 2, to stop the same, as the stylus or needle 6reaches the end of the sound groove of the record. A'nut '21 isthreaded" on the upper end of the bolt 11, to hold the circular base ofthe bracket or frame "on the bolt. Rising upwardly from the plate 7 isa'lug 22, and rising upwardly from the edge of the projection 15 ot" thebase .of the bracket is a lug 23. Connecting the upper ends of the lugs22 and :23 is a tension spring 2 l,'which, when the bracket or frame isdisposed as in Fig. 1 with the buffer out of coin tact with the;turntable, contacts slightly to one side of the center of the bolt 11,so as to hold the bufler out of contact with the table. However, whenthe frame or'bracket is tilted to the position shown in Fig. 2, thespring '24 contracts slightly on the opposite side of the center of thebolt 11, thereby holding the butter frictionally in contact with theturn table and acting to stop the same. The circular base 12 of theframe or bracket, adjacent its marginal edge, is pro- -vided with .acut-away portion 25 having shoulders 26 and 27 at the ends of the-cut-'awa ortion. The luv 22 is dis osed so as y P 2: l

IO play between the shoulders 26 and 27 of said lug, provided the recordsupporting table "be removed,"when the spring 24 has contracted on.theside of the bolt 11 nearest the table supporting spindle. However,as long as the table 22 remains :in place, the shoulder 26 remains outof contactwit'h the lug'22. Extending upwardly from the circu'lar baseof thebrac'ket or frame, is an upstanding arm'28 having a right angleextending portion 29, which is provided with an upright disposed disk.30. having a dial 31 on one face. An abutment screw 32 has its shank 33(which maybe provided with any suitable number and pitch of threads)threaded through'the centerof the :disk .30. The screwshank is providedwith a reduced part 34 on which a collar 35 is mounted. A

knurled head 36 is threaded on the reduced part 134:, to hold the collar35 closely in contact with the shoulder 37 at the point where I thereduced part 34 axially extends 'from th'efscrewr EThe collar-35in itswall has an fopening 38, "in which the angular arm or :inernber 39 issecured in any "suitable man- ";ner.
